Thanks for your response regarding the touch weight of the keys on an
upright piano.  My concern is that adding lead weight to the keys will
create another problem.  Since this is a player piano, the keys are
weighted to depress when the weight of the action is removed from the
capstan, thus the keys depress while a roll is played.

If I were to add weight to make the touch weight heavier, I would be
shifting the balance toward the capstan (possibly crossing the center
pin fulcrum point).  Adding weight might prevent the key from
depressing during roll playing.  I guess that I just don't have a feel
for how much weight I need to add and how close I will get to the
balance point of the keys.

I will do a bit of research on how much weight is necessary to adjust
the touch verses how much weight is going to shift the center of mass
across the fulcrum.

Thanks, as always, for your sage advice.  You are very generous with
your expertise and guidance.

Sincerely,
Larry Toto
